BRICKLAYERS JOINTER.

Application fi led August 3, 13 25.

To all whom it may concern:

Be it known that I, iB unnnnn J. KAEN, a citizen of the United States, residing at the city and county of: Denver and State oi Colorado. have invented certain new and useful Improvements in Bricklayers Jointers; and I do declare the following to be a full. clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this application.

This invention relates to improvements in jointers of the type used by bricklayers to finish the joints between the different layers of bricks.

In laying brick walls the layers of brick are separated from each other by a layer of mortar that varies somewhat in thickness.

The appearance of the finished wall depends somewhat upon the finish given to the separating strip of mortar. For the best work it is customary to finish the joint between the brick layers by drawing a round iron bar along the joint; this gives the mortar a smooth finish having a slightly concave outer surface. As the thickness of the mortar varies, it becomes necessary for a bricklayer to have at least two sizes of jointing tools as the one that is suitable for the narrow or thin mortar layer is too small for the thicker layers.

It is the object of this invention to produce a jointer that shall be of neat substan tial construction and which is reversible so as to provide tools of two different sizes which is usually sufficient for all ordinary wall construction. It isalso very important in a tool of this kind to construct it in such a way that it can be held firmly so as to prevent it from turning in the hand when it is used because if it should accidentally rotate in the hand while it is used, the hand in which it is held is liable to be badly in jurecl by coming into contact with the wall.

My invention can be most clearly described and will be most readily understood when reference is had to the accompanying drawing in which the preferred embodiment thereof is shown and in which:

Fig. 1, is a plan view of thepreferred form of my invention showing the manner of holding the same and Serial No. 47,756.

is a section taken on line 2 2.

2 Fig/l.

My improved jointing tool consists of two round bars 5 and 6 of identical shape and length, but of different diameters. In practice bar 5 is one-half inch in dia ietcr and bar 6 three-eight-hs of an inch in diameter. although the diameters may be varied from this without departing from the invention. The bars 5 and 6 have a straight central portion with curved ends '7 and are connected one to the other by means of parallel rods 8 which are autogenously welded or brazed to the bars at 9. Located between the bars 5 and 6 and slidably connected to the rods 8 is a wooden handle 10 of somewhat oval cross section like tlat shown in Fig. 2. The handle 10 narrower than the space between the bars 5 and 6 so that the operators fingers may extend through. the space in the manner shown in Fig. 1. If it is desired to use the large bar 5, then'the handle is moved over towards the small bar 6 and this bar as well as the handle 10 is grasped by the user. It is evident that on account of the oblong shape of the combined handle 10 and bar 6 (see Fig. 2) the tool may be securely held against turning which assures that the tool may be used without danger of twisting in the hand so as to cause the users fingers to come into contact with the wall surface and be injured. If it is desirable to use smaller rod 6 for the jointing operation, the handle is slid over to the dotted line position shown in Fig. 2 in which case the operator holds the tool by grasping the bar 5 and the wooden handle 10. The tool is used by sliding one of the bars along the joint between the bricks while the mortar is still soft so as to smooth the mortar surface and shape the same.

I desire to call particular attention to the advantages attained by means of the construction illustrated in Figs. 1 and 2. In the first place the tool is double, that is it has two rods 5 and 6 of unequal diameter which adapts it for all usual wall construction. The handle 10 which is movable towards either one of the bars 5 and 6 forms with one or the other of said bars a handhold of such shape that the tool can be held against accidental rotation in the hand. Be-

sides this, the tool is exceptionally light and 1 strong and is of pleasing design.

Having now described my invention what I claim as new is:

1. A tool for use in finishing joints in brick walls, comprising, in combination, two bars of unequal diameters connected together at points near their ends by means of two parallel rods and a handle slid-ably connected with each oi said rods and adapted to be moved towards either one of said bars.

2. A tool for use in finishing joints in brick walls, comprising, in combination a pair oi? bars of difi'erent diameters and hav ing each a straight central portion and curved ends, said bars being held in substantiall parallel relation by means of two spaced parallel rods whose ends are welded to the bars at a point near their ends and a handle slidalily connected to the rods and adapted to he n'iored into contact with either of the bars.

In testimon x whereof I afiix my signature.
